Letters Patent No. 93,360. lated August 3, 1869.

To all whom it may conoernf.

Beit known that I, WILLARD. H. SMITH, of the nity, county, and State of New York, have made certain new and useful Improvements in`Vapor-Burners; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanyingdrawings, making part of this specification, iu whichl Figure l'reprcsents a vertical -central section in line with-the slit of avapor-bnruer made with my improvements.

Figure 2 is a side view of the same.

Fig-'ure 3, a vertical section of the samey across the slit ofthe burner, and shown on an enlarged scale.

Figure 4 is, a diagram, showing a cross-section of the heater-wings of the burner.

' Similar letters of reference ndicate corresponding parts in the several ligures.- y

Irr vapor-burners the'n'iost 'important and diicult requisition is a device combined with the burner for producing 'suflicient heat to the burner in such amanner as to generate the gas properly, and to have a -large, steady, and brilliant flame that does not smoke l or smell.

To accomplish these ends many unsuccessful attempts have been made, as they either lacked generating power, or else obstructed the flame.

'I he nature of this invention consists, lirst, in the construction of heater-wings cfa peculiar form, with which the top of the burner is furnished, the same being so arranged and applied to the tip of the burner, and of such large heating-surface that the llame acts ou both sides and through them, causing en couraged draught in the llame, while they are at the same time not obstructive to the' lighti produced by the burner, whereby the desired efi'ect of a suf`- licient generation of gas and supply of' oxygeiflbr a large, brilliant, and steady flame, is obtained without objectionable defects, also dispensing with any extra healer or gas-jet.

It consists, seeondl y, iu the en'iployment of a peculiar device for regulatingr the supplyv in the air-tube, so constructed that a portion of the same remains constantly across the tribe for obstructing and mixing the current of air .and gas before reaching the flame, (having the advantage over the present regulatingscrew, which, when withdrawn, allows the jet of gas to rush up to the orifice and make the llame'ra fged,) and at the same time being fastened at both ends, it cannot be entirely withdrawn land lost from the burner.

"Iocnable'others skilled in the art to make and use my improvements, I will proceed to describe their construction and operation.

A, 'n the drawings, represents the' ordinary air-tube.' 'lhe upper extremity is furnished with the tip B, pro-l vided with the usual slit forthe out-let of the gas. Or'r its lower extremityit is jointed with the socket of the burner, and has the usual passages, D D, for the supply of air.

E represents a portion of the gas-generating chamber, which connects, by means of the passage F, with the Valve-opening or seat O, in which the upper por-- tion of the screwvalvc G is fitted, while its lower part is provided with the usual screw-thread ittedf in the socket of the burner.

Now, in order to provide for sufficient heat for gcnerating the gas, and for'- .the better supply of oxygen in the llame, I arrange aud form on each end of the slit in the tip ofthe burner peculiar outward and upward curved projecting wings, H H, which may be either slotted or drilled, in order to keep the dame united.

In order to guide the flame underneath these wings, so as to obtain a greater amount of heat, I turn their sides downwards, 'as shown in fig; 4; also that thc gas may' escape and burn both above and below the heaterwings, as shown in g. 1.-

It will be clearly observed, that by arranging anil' forming the heater-wingsH H, asabo've described, the same do not objectionably obstruct the light-,while they are' electively heated by the ame presenting a'larger heating-surface' and being in contact with the flame on both sides, and cannot he al'ected by'a draught. f

K represents the plug of metal which serves foe-mixingoand regulating the supply of air in the air-tulfeA. The same is fitted to slide across the tube A, and has a small stem, L, which passes through the one side ol" the tube, while the remainder is of ilarger diameter, and passes through the other side of the tu e A, Both ends of the plug are providedwith shoulf ers outside ofthe tube-of which the shoulder M, on the large end, servesas a handle' for regulating it bij/while the shoulder N; on the small end, serves .to prevent the plug from heilig withdrawn entirely from the .tube and bcii lost. i

The object of the enlarged part-of the plug is to reduce or increase the passage in'tlle air-tube more or less by-sllding it further in or withdrawing it, and in that manner to regulate the'flow and supply of air in the tube. The small portion` of the ,plug serves to obstruct the passage in the air-tube, and thereby di vide and mix the flow of air and vapor wlicnthe larger light, substantially in effect and for the purpose herein stated.

2. The employment of the plug K, when constrncti ed :nid arranged, :md operating in 'combination with the :tir-tube A, substantially as and for the purpose herein described.
